The NEMA 4X / NSF Exit Sign INDWLEZU is a premium-grade, heavy-duty emergency lighting solution designed for environments requiring strict hygiene, washdown resistance, and corrosion protection. Engineered for food service operations, industrial washdown areas, and wet environments, this exit sign delivers unmatched durability, safety, and compliance.

Constructed from 5VA flame-retardant, UV-stabilized polycarbonate, the INDWLEZU features a high-impact resistant clear lens and a corrosion-resistant sealed enclosure with an engineering-grade silicone gasket. This robust design ensures reliable performance even in harsh, high-moisture, and chemically exposed environments.

The unit utilizes ultra-bright, energy-efficient LED technology with field-selectable red or green illumination, ensuring high visibility and code compliance across various facility requirements. EZ snap-out chevron directional indicators allow quick configuration for directional guidance.

Designed to meet stringent industry standards, the INDWLEZU is NEMA 4X rated, providing protection against corrosion, windblown dust, rain, splashing water, and hose-directed water. It is also NSF certified for food service operations, making it ideal for commercial kitchens, processing facilities, and sanitary environments. Additionally, it is UL listed for wet locations, ensuring full safety compliance.

For emergency operation (EM models), the system includes a 4.8V maintenance-free NiCd battery that delivers a minimum of 90 minutes of emergency illumination. A solid-state transfer switch ensures immediate activation during power failure, while the automatic two-rate charger restores battery capacity within 24 hours.

A bi-color LED indicator provides real-time system status (green = normal, red = battery check), while a push-to-test switch enables quick and easy compliance verification.

Installation is simplified with rear surface wall mounting hardware, along with conduit knockouts for flexible wiring entry. The sealed enclosure design ensures long-term reliability in demanding environments where moisture and sanitation are critical.

This model is fully certified and compliant with CEC Title 20 energy regulations, making it a dependable solution for regulated commercial and industrial applications.
